I've made 3/4 fit into 1" pipe before by softening it in boiling water, that and the fact that the piece of 1" that I'm using won't be any longer than 1 1/4 inches, so it won't be hard to get onto the pipe. That and the fact that theres a section at the bottom of the 1 and 3/4 inch pipe cut away, it...

Building off of Davidvaini's Preloaded Cartridge Prototype, I figured I'd try and figure out a way to make it triggerable... Link to Preloaded Cartridge: http://www.spudfiles.com/forums/preloaded-cartridge-prototype-t14802.html Any commetns or questions just ask, I'd explain more but I gotta go visi...

Plexi could work, but I'd reinforce it with something, maybe a bit of epoxy if you can spare it, but if you can't I don't think it'd be too bad.

Not the lazer beam part, though.

Are you being sarcastic?

I didn't say you were bashing me or anything, I just thought that the forums would be more helpful. This is why I haven't really posted that much.

Oh my bloody god...I never said I was the first to do anything like this, in fact, I was counting on it. I simply posted an idea, hoping to get feedback as to whether or not it would work, not who built it first. I seriously think that that isn't the issue, I think if you guys stop fighting over who...

By the way, why did yours fail?

The difference between your built design and my design (besides the fact that one actually exists) is that the top part where rounds are loaded into is threaded with a threaded endcap.

Might need some work, but here's my theory...

Actually, homedepotpro, if that happened then the pop-off valve would kick in.

Hmmmm...I just had an idea. Take the propane injection system and put that further up, say in the front part of the gun, threaded into the coupling/bushing and pipe. Then replace the pilot valve with a schrader With that there, you pressurize the piston to be like your burst disk. The area behind th...

I may try to make one, but I'm going to make it out of 2 inch pipe first, and after I have the design right, I think I'll try to make it out of 4 inch pipe. I'm not sure about you, but I'm going to try to make mine able to rotate the barrels the way they rotate around the center axis and also try to...

What's the solvent welding course?

Sorry, I wasn't aware of the limit on what you discuss. I'll only say that there is a way for a firework to damage like that, but that is all I'll say, that and that I apologize for posting that, I guess I'll have to read the rules a bit more thoroughly
